I'm very glad you made this topic and that the community here is generally ok with this. I completely agree that when a hack that's unfinished, hasn't been touched in years and basically abandoned, it's ok to try and finish it so long as you give the original creator credit. This way at least people can enjoy the hacks, and some of them are actually pretty amazing.
I've actually done this to two Mega Man 2 hacks already. I kept them to myself because I recall reading on another rom hacking forum that this is frowned upon(finishing another person's hack). So, I never released them. But I think this is a good time to do so here.
I've made these two MM2 unfinished hacks so that you can actually play through them from beginning all the way to the end:1) Rockman 2 Deluxe Ver (use GoodNES 3.14 - Rockman 2 - Dr. Wily no Nazo (J) [!])
For this one, I basically reworked the tiles and a few items/enemies for Wily 3 so that the stage isn't a jumbled mess. You can now easily navigate and play through it normally and get to the rest of the game.
REMOVED - Will update with a newer/complete version in the future.2) Mega Man 2 Wily's Conquest 2 - v0.9 (user GoodNES 3.14 - Megaman II (U) [!])
The unfinished version of the game ends after Wily 3. As soon as you begin in Wily 4 you are surrounded by death tiles so you are unable to go on. None of the Wily 4, 5, and 6 levels are done. The original MM2 Wily 4 and 5 levels are left intact in the rom, so I brought them back with some edits to take advantage of MM's added speed. I completely redesigned Wily 4's boss for this as well. Wily 6 was partially hacked, but appeared to be intentionally 'blocked off'. I opened it back up and put the stage back together with a few of my own edits also with MM's new speed in mind.
I have always been fascinated with this hack as it speeds up MM's movement much like Burst Chaser. However, this came out in 2002 so that's pretty amazing, and I prefer MM1&2's gameplay/physics over MM3-6 so I've always wanted to play through this one. With that said, the original hack of the robot master stages aren't without problems. With the added speed, you'd think this hack would be a blast to play through. But the original version of the hack was littered with bad enemy placements and at times just way too many enemies in each section, making the game less than enjoyable in many areas to play through. For this reason, I'm keeping the version number at 0.9 for now. When I have the time, I would love to come back and 'clean up' the rest of the hack and the stages for a better experience.
Ok that's all I have for now. I've attached the IPS files for the two hacks. Feel free to give them a whirl and let me know what you think!
I'll likely submit these two hacks to the site later also.
